Wire shear anvil tool

Abstract

A portable wire shear anvil tool is disclosed having a main body, a threaded plunger with a shear plunger at one end, a movable upper shear blade, and a lower shear blade or anvil fixed in place. Upon actuation of the wire shear anvil tool, the tool is adapted to engage and to shear a wire, which can be of differing diameters.

It is claimed: 
     
         1 . A portable wire shear anvil tool comprising
 (a) a main body including an outward extension having a threaded passage therethrough, and a lock piece;   (b) a threaded plunger adapted to be received in and move in the threaded passage in the outward extension of the main body, said threaded plunger including a tool receiving opening in a first end thereof;   (c) a shear plunger at a second end of said threaded plunger;   (d) an upper shear blade fastened to said shear plunger so as to move with the shear plunger; and   (e) a lower shear blade fixed in place to said main body by said lock piece.   
     
     
         2 . The portable wire shear anvil tool according to  claim 1  further comprising a thread lock at or adjacent the first end of said threaded plunger, said thread lock being adapted to limit movement of said threaded plunger into said threaded passage. 
     
     
         3 . The portable wire shear anvil tool according to  claim 1  wherein said main body includes a guide groove in which one side edge of said upper shear blade is received in and adapted to move in upon movement of the threaded plunger. 
     
     
         4 . The portable wire shear anvil tool according to  claim 1  wherein said tool receiving opening in said threaded plunger is adapted to receive a ratchet tool for providing downward and upward movement of said threaded plunger in said threaded passage in said outward extension. 
     
     
         5 . The portable wire shear anvil tool according to  claim 1  wherein said second end of said threaded plunger includes an opening adapted to receive and hold said shear plunger. 
     
     
         6 . The portable wire shear anvil tool according to  claim 1  further comprising a support bracket including a fastening element for retaining in an operative position said portable wire shear anvil tool on said support bracket. 
     
     
         7 . The portable wire shear anvil tool of  claim 6  wherein said fastening element is an upraised post having a spring loaded ball detent on one side of the post.
